Features

• Fields of application The actuator is particularly suitable for utilisation in outdoor applications and is protected against the following weather conditions:
  – UV radiation
  – rain / snow
  – dirt / dust
  – humidity
  – Changing atmosphere / frequent and severe temperature fluctuations (recommendation: use the actuator with integrated factory-installed heating which can be ordered separately to prevent internal condensation * {in development})


• Mode of operation The actuator is controlled with a standard modulating signal of DC 0 ... 10 V and travels to the position defined by the control signal. The measuring voltage U serves for the electrical display of the damper position 0 ... 100% and as slave control signal for other actuators.


• Simple direct mounting Simple direct mounting on the damper spindle with a universal spindle clamp, supplied with an anti-rotation strap to prevent the actuator from rotating.
  
  
• Manual override Manual override with pushbutton possible (the gear is disengaged for as long as the button is pressed or remains locked).
  
  
• Adjustable angle of rotation Adjustable angle of rotation with mechanical end stops. Standard setting 0 ... 90°. The housing cover must be removed to set the angle of rotation.
  
  
• High functional reliability The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.
